Onboard ESP8266 11 WIFI module has three types of work: STA (client), AP (heat
Point) and STfA + AP (client + hot), according to the work of the module to select the corresponding WIFI model
Head to work mode.
Before using the need to use serial debugging software and USB to TTL module to send serial port instructions on the WIFI module into
Line configuration (after the completion of the configuration do not power, because the WIFI module after some of the parameters can not be saved)

Electronic Dice NE555 CD4017 DIY Kit 5mm Red LEDs 4.5-5V ICSK057A Electronic Fun Kit $2.19
Vendor: e_goto Processor store (IC Station) circuit
ICSK057A Precise Electronic Dice DIY Kit 7pcs 5mm Red LEDs
Electronic dice kit is based on the NE555 oscillator circuit and circuit CD4017 counter display kit.
1. Kit parameters:
Supply voltage: 4.5-5V
Dimensions: 74 * 35mm
When a power-up, 7 LED will randomly display a number of points, players press the switch S1,7 all lit LED only after about 7 seconds LED light starts blinking, until finally showed stable points. Throughout the end of the first “crap” process.
Circuit mainly by the pulse generator and a decade counter circuit. Pulse generator and external elements by NE555 multivibrator, when you press the button S1 when Q1 turns on, the output pulse NE555 3 feet, then five turns the output CD4017 output high, resistors and transistors by different combination, can drive seven LED light to indicate the number of points 1-6 points.

Adafruit Raspberry Pi Zero Case $4.75
This is a basic, classic Pi Zero enclosure with a black base and a clear top. The case is as minimal as it gets, coming in just two pieces of polycarbonate that snap snugly together. This case will keep your Pi Zero safe and secure while also looking super sleek. You can use all of the connectors on the edges of the Pi: mini HDMI, microSD slot, microUSB power, and microUSB port. There’s also a cut out to allow a 2×20-pin header to be soldered onto the Pi Zero.
The enclosure was designed by Mike Doell – just like our elegant, beautiful, and functional Pi Case for Raspberry Pi Model B. Made of ultra-durable, super-glossy polycarbonate, it is both good looking and tough enough to toss into your pocket, bookbag, or toolbox. It has slim openings for all your cables, an easy-to-access slot for your Micro SD card, slots for your Pi Camera, and a space for your GPIO cable to extend out from the Pi.
The Pi sits nicely in the base, latching to the corner pegs, and the lid fits snugly on top. If you want to break-out your Pi you can simply snap off the GPIO slot and add pHATs, Bonnets, GPIO cables and other accessories with ease.
Raspberry Pi Zero W $10
If you didn’t think that the Raspberry Pi Zero could possibly get any better, then boy do we have a pleasant surprise for you! The new Raspberry Pi Zero W offers all the benefits of the Pi Zero v1.3, but with one big difference – built-in WiFi!
More specifically, this giant upgrade is the addition of a BCM43143 WiFi chip BUILT-IN to your Raspberry Pi Zero – just like the Pi 3! No more pesky WiFi adapters – this Pi is WiFi ready. There’s also Bluetooth Low Energy (BLE) on board making the Pi an excellent IoT solution (BLE support is still in the works, software-wise).
